Express the product as a sum containing only sines or cosines for question 14. Express the sum or difference as a product of sines and/or cosines for question 15

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

(x) - (y) = (1 + 4i)
